Answer:
maximum income is $900
Explanation:
given data
oil change = $20
per day = 40 customer
increase = $ 2
dailer customers = 2
owner charge = $ 2
to find out
income from the business
solution
we know current income is 40 × 20
current income = $800
we consider here price increase x and income as function y
so y = (20 +2x) × ( 40 - 2x) ........1
y = −4x² + 40x + 800
take derivative and put dy/dx = 0 for maximum
dy/dx = -8x + 40
0 = -8x + 40
x=5
so here from 1
y = (20 +2x) × ( 40 - 2x)
y = (20 +2(5)) × ( 40 - 2(5))
y = 30 × 30
y = 900
so maximum income is $900
